During later stages, Sekkizhaar built a temple for Lord Shiva at Kunrathur which is very similar to the Thirunaageswaram temple. He installed the deity (Shiva Lingam) with Naagaabaranam (snake as an ornament) around the Shiva Lingam and named the Lord as Sri Naageswarar.

This temple is also popularly called as Vada Thirunaageswaram.

This temple is considered the Raahu Sthalam among 9 Navagraha Temples of Chennai (or Thondai Mandalam). The Naagar around the deity is considered the Raahu for worship. Parihaarams (remedial worship) for Raahu are done here, especially during Raahu Kethu Peyarchi and also during Raahu Kaalam (4.30 PM to 06.00 PM) on Sundays.

The temple is very huge and wonderful. The vast praakaarams add beauty to the temple. Sri Naageswarar is seen facing east and Goddess Sri Kamakshi is facing south. Sri Sekkizhaar also has a separate shrine inside the temple.

A magnificent Dwajasthambham is located on the eastern side of the temple, straight to the entrance.

Sri Nandhigeswarar is seated in a small stone mandapam and is facing east towards the sanctum.

Sthala Viruksham (holy tree) for this temple is Shenbaga Maram and Theertham is Surya Pushkarani. Surya Pushkarani is very large and beautiful which is seen outside the temple on the south eastern side.
